To al?, whom t may concern:

Be it known that I, WALTER H. LUM, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Hat Tip RubbingMachines, of which the following is a specification.

This invention relates to a machine for removing the surplus gold,silver, or other metallic leaf used as a finishing or coating forcertain kinds of printing.

The invention will be particularly described and referred to inconnection with the finishing of what are known as Hhattips or thelabels which are inserted in mens hats and which contain the imprint ofname and address of the maker or seller, although I wish it to beunderstood that the same operation may be applied to the printedportions of any material or device, such as silk or satin badges, inwhich metallic leaf or dust is applied to color the printed matter. Theinvention involves mechanism for rubbing the tip or other printed deviceso that the surplus gold leaf or powder is quickly removed withoutmarring the print in any way. As at present carried on this result isaccomplished by handwork, the operator using a piece of cloth andrubbing the printed surface several times until the surplus leaf orpowder is removed, except where it adheres to the printed characters.

In the accompanying drawings I have shown preferred embodiments of myinvention in the following figures.

Figure 1 is a view, partly in side elevation and partly in longitudinalsection, of a machine embodying my invention in one form. Fig. 2 is atop plan vi ew of the parts shown in Fig. 1. Fig. 3 is an elevation ofone of the guideways or tracks as used in my machine.

Fig.. Il is a top plan view showing a modified form of carriage forming.a part of my machine, and Fig. 5 is a side elevation of the parts shownin Fig. 4.

Referring to the drawings in detail, a represents a flat-top tablesupported at the four corners by legs a and having throu h the top anopening a2, below which is slidabIy mounted a draw a4, to which issecured a handle a5. On the top of the table in front of the opening a2is secured a pad a3. Secured in the table-top are two posts b, the upperends of Which are connected by a cross-bar b', and

bolted to the rear end of the table is a twoarm bracket, in the outerends of which is mounted a pulley d, over which travels a belt d', whichis driven from an overhead shaft or pulley in any convenient manner. Onthe ends of the shaft upon which the pulley d is fixed are crank-arms c,to the outer ends of which are secured rods c2. Secured to the top ofthe table are channel-irons e e, having' an upper flange e and a lowerflange e2, which form a guideway or track for a movable carriage to bedescribed. The upper flanges are cut away at c3 and e4, and on the upperflange adjacent to the cut-away portion e* in each of the rails e is apivoted link e5, which is inclined rearwardly and has its lower endresting on the flange e2, forming an inclined plane, as clearly shown inFig. 3. Between the tracks formed by the channelirons e e is slidablymounted a carriage which is composed of side bars f, a front cross-barj", and a rear cross-barf2, all rigidly connect- `ed together to form arectangular frame. The side bars f extend forwardly ofthe crossbarjl2and have formed therein bearings for the shaft of the roller-brush g.The rear ends of the side bars f have upward extensions f3, in which ismounted a shaft f u, which carries a yoke f4, upon which are mountedgrooved rollers f 5. A portion of the shaftj'1l is surrounded by aspiral spring f G, one end of which is secured in the side barf, and theother end bears against the under side of the yoke f4, so that thetension of the spring is exerted to hold the yoke upward, as clearlyshown in Fig. 2. At the rear side of the cross-bar f2 are lugs f7,between which are pivoted the forward ends of the rods or links c2. Thecarriage is mounted on the rollers f1", which run between the upper andlower flanges of the track-bars e until in the forward movement of thecarriage they reach the inclined links c5, when said rollers ride onsaid links and along the upper flange c until they reachV the cut-awayportion e3, when they drop to the lower flange.

In Figs. l and 2 I have shown means for rotatin the brush g and forsupporting the forwar end of the carriage, which I will now describe. Onone end of the brush-shaft is mounted a pulley g, over which travels around belt g2, which passes under the grooved pulleys f 5 and is drivenby suitable pulleys on an overhead shaft. (Not shown.) The belt g2 iskept taut by a coil-spring f acting on IOO the yoke f4, as heretoforedescribed. In order to cushion the drop of the carriage through thecut-away portion e3 at the end of its forward movement, I provide acylinder 7L, hinged at h2 on the cross-bar b and having working thereina piston h, the lower end of which is pivoted to the cross-bar f of thecarriage. The head of the piston fits sufficiently tight in the cylinderh to cause more or less resistance to the downward drop of the carriage,as will be readily understood.

In Figs. i and 5 I have shown a modified method of driving the brush,which consists of grooved pulleys g4, secured to the rollers at the rearof the carriage, and pulleys g', secured to the ends of the shaft-brushg. Endless belts gwhich travel over said pulleys g and g4 on each sideof the carriage, and the rotation of the rollers f 1 asthey are drawnbetween the flanges e e2 drive the grooved pulleys g4, hence transmitmotion, through the belts g2,to the pulleys g. The rear crossbar f2 ofthe carriage is provided with an eX- tension f 8, upon which isadjustably mounted a counterweight fg, which servesto balance the weightof the forward part of the carriage and the brush, thus preventingviolent dropping of the brush in the forward movement of the carriage.

In the operation of my machine it will be seen that the carriage isreciprocated between the tracks e by the action of the drive-rods c2,driven from the cranks c on the shaft of the pulley b. In the forwardmovement of the carriage the front rollers ride up on the links e5 andalong the upper iiange e until they reach the cut-away portion e3, whenthey drop, and thereby permit the brush g to come in contact with theprinted tip or other device that-has been placed on the mat a3 for therubbing operation. The roller is then rotated in the direction indicatedby the arrow in Fig. l, whereupon the surplus goldleaf or other materialapplied as a coating to the printed tip is removed by the revolvingbrush and caused to fall into the drawer a4.

The carriage then retreats and a new tip is placed in position for asecond similar operation.

So far as I am advised, I am the first to provide a machine foraccomplishing the results above described, and I therefore do not wishto be limited to the specific construction shown and described; but

What I claim, and desire to secure by Letters Patent, is-

l. In a machine of the class described, a table, a reciprocating andtilting carriage arranged above the table, a brush rotatably mounted onsaid carriage, means for rotating the brush and means for reciprocatingand tilting the carriaffe.

2. In a machine of the class described, a table, a reciprocatingcarriage adapted to be raised at one end and to fall by gravity, meansfor modifying the action of gravity on the carriage, and means forreciprocating the carriage.

3. In a machine of the class described, a table having an openingtherein, a slideway secured to said table, a carriage adapted toreciprocate in said slideway, a cylindrical brush rotatably mounted atthe forward end of said carriage, means for reciprocating the carriageand means for rotating the brush.

4:.- In a machine of the class described, a table, a slideway secured tosaid table, a carriage adapted to reciprocate in said slideway, meansfor raising the carriage in its forward movement, a brush mounted at theforward end of said carriage and means for recipro cating the carriage.

5. In a machine of the class described, a table, a slideway secured tosaid table, a carriage adapted to reciprocate in said slideway, means insaid slideway for raising the carriage in its forward movement andpermitting it to drop in its rearward movement, a brush mounted at theforward end of said carriage and means for operating said carriage.

6. In a machine of the class described, a table having an openingtherein and a drawer arranged under said opening, a slideway secured tosaid table and extending along each side of said opening, a carriageslidably mounted in said slideway, means for raising and lowering thecarriage relative to said slideway, means for sliding the carriage, acylindrical brush rotatably mounted in said carriage and means forrotating said brush.

In testimony whereof I affix my signature in presence of two witnesses.
